I like 505 the best, although I have a hard time finding it in the local stores.
June Tailor is ok. I have to use a lot to get everything to stick together.
The Sullivan's brand works well, but it smells AWFUL and it has a lot of overspray. I feel like this one can't really be used safely inside as it gets on everything and makes clouds when you spray it.
I haven't tried the Sulky, although I do like some of their other products I have tried like embroidery stabilizers.
